Direct Drive
Most of the fans we build are driven by electric motors, and this requires the fan wheel and/or shaft to connect with the motor shaft in some way. There are two broad classifications we use to describe this connection – 1) belt drive and 2) direct drive.
What is an Arrangement 4 Fan?
Fan arrangements, based on AMCA standards, define the way a motor drives the fan, and how the motor mounts to the fan. An Arrangement 4 Fan is a direct driven fan with the fan wheel mounted to the motor shaft.
Determining the Optimal Drive for Your Industrial Fan
What makes your industrial fan whir? It’s a motor connected to your fan in one of only two ways: direct drive or belt drive. In the former, the motor connects to the fan wheel with nothing in between. In the later, there is a belt (sometimes more than one) connecting the motor to move the fan.
